"sections" argument is not being parsed in CLI

[arvitus]

Describe the bug MCA CLI doesn't process the sections argument in import mode. When running this command in the windows command line mca imports the whole chunk instead of just the specified sections: java -jar <path_to_mcaselector.jar> --mode import --world <path_to_world> --source-world <path_to_world> --sections "-4:-1"

This is because the sections argument actually never gets parsed as it's not even a valid option. When running mca with the --help argument, the sections argument is not in the list of the valid arguments. In the responsible source file is simply a section like this missing:

options.addOption(Option.builder()
    .longOpt("sections")
    .desc("One or a range of section indices.")
    .hasArg()
    .build());

So adding this would fix the bug.

To Reproduce Steps to reproduce the behavior: Run MCA CLI in import mode and specify a selection using --sections <range>. Check if only the specified sections were imported.

Expected behavior MCA CLI does process the sections argument in import mode.

Environment (please complete the following information):

• OS: Win 10
• Java version: 17.0.2
• Version of MCA Selector: 2.1
